In chemistry, a salt is any neutral chemical compound made of cations (positive ions) attached to anions (negative ions). The main kind of salt is sodium chloride with the chemical formula NaCl. It is formed when hydrochloric acid is added to sodium hydroxide. The reaction is as followsHCl+NaOH2 gives NaCl+H20+heat
Mixtures of salts in water are called electrolytes. Electricity is able to pass through electrolytes, as well as molten salts.
